  • SCOPE

    1 Scope

    1.1 These requirements cover foam producing equipment and liquid concentrates employed for the production and discharge of foam that has an expansion ratio of 20:1 or less and is used for fire extinguishment. These requirements are based on the premise that foam equipment and specified types of foam liquid concentrates with which they are intended to be used are to be investigated for use with each other.

    1.2 If foam equipment covered by these requirements incorporate sprinklers, the sprinklers shall comply with the Standard for Automatic Sprinklers for Fire Protection Service, UL 199 .

    1.3 Requirements for the installation and use of foam equipment and liquid concentrates are included in the following standards of the National Fire Protection Association:

    a)     Low Expansion Foam and Combined Agent Systems , NFPA 11 ;

    b)     Deluge Foam-Water Sprinkler and Spray Systems , NFPA 16 ;

    c)     Installation of Closed-Head Foam-Water Sprinkler Systems , NFPA 16A .

    1.4 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire, electric shock, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements to determine that the level of safety as originally anticipated by the intent of this standard is maintained. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard shall not be judged to comply with this standard. Where appropriate, revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
